The hump is not that big of an aerodynamic issue because the flow is already distorted because of the front wing and the nose itself. The aerodynamic gain of such a small fluent form of the hump is to be said nothing.
Im more curious on wether our extreme small hood has any big gain. Im still amazed by the small package Williams delivers, mainly due to the small gearbox which no one has copied yet.

After two below-par years with Cosworth engines, the team signed a new deal with Renault towards the end of 2011 which means this year's FW34 is the first Williams since the championship-winning FW19 to be powered by the French manufcaturer.

"The engine is just a lot more flexible," Gillan said at last week's Barcelona test. "It's definitely a decent step. Working with Renault is very good; they are a very professional outfit. Both of us are still learning each other's processes, but things are going well. Very, very pleased."

One of the weak points on last year's car was its performance in slow-speed corners. Gillan said a reconfigured rear end and the new Renault engine had helped solve that problem.

"A lot of it is down to a better, more stable aerodynamic platform, because although they're slow [corners] aerodynamics are still important. Indeed, it's probably even more important in the slow speed because that's where the lap time is to be had. That plus the tractability and flexibility of the engine through its range helps as well, it's a mixture of the two."

And he revealed that this year's car is a completely different beast under the skin.

"It looks similar, but if you were to see the car without its bodywork it is significantly different to last year's," Gillan added. "We have gone through every area to see where we are losing performance. So we had a reasonably bad cooling performance and when it got hot we lost quite a lot of performance. We've spent a lot of time dealing with that and improving the bodywork."

Is it going too far to suggest that the exhausts appear to be blowing onto the top of the lower rear wing element?

That is going off TerraNova19's link, the angle of the bodywork opening, and the fact that from the angle the shot is taken- ie, looking down on the exhausts through the top of the lower rear wing element, the pipe appears perfectly circular.

Let the criticisms come flooding in!

You are not mistaken - Blowing the rear wing - top or bottom...

I forget where I read it but it (Scarbs most likely) that Williams were testing that solution out with last year's FW33 during December & we would eventually see it on the FW34.
